RAZOR-HON E.

Specification of Letters Patent.

Patented A11 30, 1921.

Application filed April 26, 1919. Serial No. 292,857.

T 0 all whom it may concern:

Be it known that I, EDWARD J. SAWTELLE, a citizen of the United States, residing at Berwick, in the county of York and State of Maine, have invented certain new and useful Improvements in a Razor-Hone, of which the following is a specification.

This invention relates to improvements in hone devices for sharpening razors and like cutting edge implements, and has for one of its objects to simplify and improve the construction and increase the efficiency and utility of devices of this character.

Another object of the invention is to provide an improved arrangement of plates of metal possessing suitable honing qualities, the metal members being of varying'degrees of hardness and arranged in suitable posi tion for convenient or consecutive use, the metal members being backed by suitable yieldable material such as felt flannel or the like.

With these and othen objects in view the invention consists of certain novel features of construction as hereafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a perspective view of the improved device, and,

Fig. 2 is an edge view enlarged of the same, and,

Fig. 3 is a detail illustrating a modification of the construction.

This invention has for its primary object to utilize the honing qualities of certain metals of varying hardness when oil, water, or other suitable lubricants are applied thereto, the plates being arranged in convenient position for consecutive use. The harder metal is first used for the first honing and the softer metal used for the second or finish honing.

The metal members are relatively thin and backed by suitable yieldable material such as felt flannel or the like, the latter being rigidly supported by a suitable block or base, preferably wood.

Experiment has shown that aluminum operates satisfactorily for the harder metal and zinc for the softer or finishing metal. The metal is sufficiently thin to slightly yield when pressure is applied thereto by the honing action, so that the edge of the razor will be brought into closer contact with the honing surface.

The thin metal members, the yieldable backing members, and the rigid base or foundation members may be of any suitable size or proportions, but generally the rigid base or foundation member will be of wood as indicated at 10 with its side faces in parallel relation and with the yieldable members bearing upon the opposite faces as indicated at 11 and 12, with the zinc member represented by 13, bearing upon one of the yieldable members and the aluminum member represented at 14, bearing upon the other yieldable member. By this arrangement the two honing surfaces are supported in convenient position for consecutive use. The members may be connected in any suitable manner, but will preferably be cemented to the block and to each other, but it is not desired to limit the invention in any manner in this respect. F or instance the members 13 and 14 may be extended at the ends and bent over the ends of the block 10 and secur'ed thereto, as shown at 15 and 16 in Fig. 8.

Having thus described the invention what is claimed as new is:

A hone of the class described comprising a rigid supporting body having opposite rectilinear faces, a thin plate of sheet metal of uniform thickness and capable of serving as a sharpening element for edge tools mounted on each of said faces and being sufiiciently thin to yield slightly to the pressure applied during the sharpening operation, and yieldable pads of uniform thickness throughout disposed between the plates and the body and presenting a uniform yieldable resistance to the pressure on the plates.

In testimony whereof, I aifix my signature hereto.

EDXVARD J. SAWVTELLE.
